PRICE-INDICATING ATTACHMENT FOR WElGHlNG-SCALES.

SPECIFICATION forming part of Letters Patent No. 489,942, dated January 17, 1893.

Application filed April 11,1892. $erial No. 428,746- [No model.)

To aZl whom it may concern:

Be it known that we, WILLIAM H. GAMBLE and DAVID H. ALLEN, citizens of the United States, and residents of Miamisburg, county of Montgomery, and State of Ohio, have invented a new and useful Improvement in Price-Indicating Attachments to TVeighing- Scales, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification.

Ourinvention relates to an improved computing, or price-and-value indicating attachment for weighing scales, by the use of which the operator may readily determine the value, at any or all of a list of prices, of goods weighed on the scale to which the computer is attached.

The invention consists of one or more graduated tables or leaves, attached, preferably, to an ordinary scale beam and arranged to swing or revolve around an axis running practically parallel or in a line with the scale beam, and of aweighted, sliding and graduated index or price list which extends at right angles to said axis across the face of the tables and is adapted to travel in a line with or parallel with said axis.

t The invention also consists of parts and combinations of the same, specifically hereinafter set forth and pointed out in the claims.

Referring to the annexed drawings, which form a part of this specification, and in which similar letters indicate corresponding parts in all the views, Figure 1 represents a side elevation of a portion of an ordinary scale beam with the improvement attached thereto. Fig. 2 is an end View, and Fig. 3 is a cross-sectional View of the same through the line 00-23, of Fig. 1. Fig. 4.- is a side elevation of a portion of the improvement. Fig. 5 is a crosssectional view of the same through the line m-x of Fig. e and Fig. 6 is a cross-sectional view through the line yy of Fig. 4. Fig. 7 shows V-shaped tables and indices arranged in star shape.

Referring to the drawings by letter, A represents a portion of an ordinary scale beam. The standards 13, which support the computer are attached to the beam A in any suitable manner, but preferably with bolts. The shaft D, which is provided with shoulders that press the arms or end pieces 0, passes through cir cular bearings or boxes in the standards B and is provided with threaded ends on which are adjusted the nuts G. The tables E may be fastened to the arms 0 in any suitable manner, but preferablyare clamped between the arms 0, by means of the shaft D and the nuts G, the arms C being provided with slots or grooves which engage the ends of the tables E. The tables E are com posed, preferably, of strips of sheet metal, each strip stamped on both indicating faces with suitable figures and division marks. In the manufacture of this computer, however, it may be desirable, for convenience in stamping and in order to make a stronger table, to make each of the tables of a strip of sheet metal bentinto V or U shape, as shown in Fig. 6. To accomplish this a flat piece of sheet metal of about twice the width of the intended table will be stamped on one side only, in such manner that when the sheet is afterward bent double or into U or V shape, it will form a U or V shaped bar having both indicating faces properly graduated. It will be seen that a plate or table thus formed is lighter and stronger than one made from a solid sheet of metal not so bent.

The arms 0 may consist of a single piece of metal; in this case the tables or leaves E will be held a fixed distance from each other and when one table is revolved all the other tables will revolve in unison; the whole might be compared to a paddle or water wheel, the graduated tables corresponding to the blades or paddles of the water wheel. It will be observed that when the arms 0 are thus made of one solid piece, (where the tables are not V or U-shaped and arranged in star-shape, as in Fig. 7,) more than four tables could not profitably be used, as, if more than four were used the angles formed by the indicating surfaces of the tables would be acute angles and the tables could not be read so well as when only four tables are used, in which case the angles formed by the indicating faces of the tables are right angles. However, in the course of manufacture, it will benecessary to increase the scope of the computer for certain kinds of scales and to this end it will be desirable to use more than four tables. This can readily be done and in such a Way, also, that the tables maybe easily read by making the arms 0 not of a single piece, but each arm of a separate piece, which will revolve or swing a certain distance independently of the other arms. When the arms 0 are thus construeted,it will be observed that the tables E will, each, revolve or swing a certain distance independently of the other tables. Any table selected to be read can then be turned into position suitable for reading and the other tables, on either side thereof can be revolved away from said table so that the operator will have an unobstructed view of the one selected. One manner of attaching the arms 0 so that they can be swung thus independently, is illustrated in Figs. at and 5 which are views of a portion of the computer with all the tables removed but one. The arm 0 is pivoted at e to the flange or collar (2 which is fixed immovably to or forms a part of the shaft D. It can be seen that while the shaft D remains stationary, the arm C may be thrown into several different positions as indicated by dotted lines in Fig. 5.

The sliding weight and index F on the arms of which is stamped a suitable price list, is provided with an opening in its body through which passes the shaft D on which the index is adapted to slide back and forth. From the bodyof the index an arm extends across each graduated face of the tables E.

Vhen the tables E are constructed to move in unison, the arms of the index F may form one solid piece with the body of the index. But when the tables are constructed to move independently of each other, the indicator F will have to be so constructed that each of its arms will move independently of the other arms and so that each arm will move in unison with the table whose graduated face it crosses. This construction is accomplished when the arms of the index are pivoted to the body of the index, as shown in Fig. 6, the pivot of the index being on a line with the pivot c of the arm 0.

Vhile, in the foregoing, the tables E are described as being adapted to revolve about a shaft, which is fixed adjacent to and parallel to a scale beam the effectiveness of the computer does not depend upon this exact construction. The shaft D can be attached directly to the balancing frame of a scale, and pound and ounce marks can be placed upon any of the tables E, there will then be no need of an auxiliary pound and ounce beam, or, in other words, the beam of a scale may be adapted to form the shaft D to which the arms 0, tables E and index F are attached in such a manner that they will revolve about the scale beam, which is also the shaft D.

Each arm of the graduated, sliding price list or index F may be provided with an extension tablet, as indicated at- F, showing in larger figure, the first or lowest price on said list thereby facilitating ease of finding the price list desired.

Having thus described our invention, what we claim as new and desire to secure by Letters Patent is:-

1. A revoluble price and value computer for weighing scales, attached to the scale beam in any suitable manner and consisting of a series of tables or leaves which are graduated on both sides and radiate from and revolve around a common axis, said axis extending approximately parallel to or in a line with the scale beam, substantially as described.

2. The combination with a revoluble price and value computer for weighing scales, attached to the scale beam in anysuitable manner and consisting of a series of tables or leaves which are graduated on both sides and radiate from and revolve around a common axis, said axis extending approximately parallel to or in a line with the scale beam, and a weighted sliding and graduated index or price list which extends at right angles to said axis across each indicating face of said tables and is adapted to revolve with said tables and to travel back and forth, in a line parallel with said axis, substantially as described.

In testimony whereof we have hereunto set our hands this 7th day of April, A. D. 1802.
